Which outcome occurs when a PET scan subject moves unexpectedly?

💡 Explanation

Unexpected movement disrupts image reconstruction because coincidence detection relies on precise spatial and temporal correlation of annihilation photons; the decay of the radioisotope emits positrons. Therefore, image artifacts arise, rather than accelerating decay, inducing scatter, or saturating detectors.
